Bryan Duxbury commented on THRIFT-772:
--------------------------------------
I can assure you that equals and compareTo work. We use those methods all the
time. I don't know what other fields your ThriftObj has, but you should make
all of the fields either required or optional. This will ensure that the
optional ones are *not* serialized or deserialized on either side, and the bit
vector will be correct.
Also, what version of Thrift are you using?
> __isset_bit_vector state before serialization differs from state after
> unserialization on native field

> Key: THRIFT-772
> URL: https://issues.apache.org/jira/browse/THRIFT-772
> Project: Thrift
> Issue Type: Bug
> Components: Java - Library
> Affects Versions: 0.2
> Environment: Linux, thrift release 0.2.0 with patch Thrift-746 and
> Thrift-663
> Reporter: david herviou
> Labels: serialization
> Attachments: thrift-issue-bitset-nativefields.tgz

>
> Once java classes have been generated it is possible to test if the fields
> have been set or not using the method isSetXXX().
> Once one of this java class is instanciated, all call to field.isSetXXX() are
> returning false which is a good thing (this method ask for
> __isset_bit_vector.get(XXX))
> Now if you serialize the previous object and unserialize it (without doing
> any changes on it) the following occured : all fields that corresponds to
> native data are returning true when isSetXXX() is invoked.
> Consequently, the operation unserialise(serialize(object)) is not an identity
> function.
> This is mainly due that the __isset_bit_vector is not serialize and rebuild
> during the unserialize operation.
> Any idea how to fix this ?
